Lasioglossum (Dialictus) julipile Gardner & Gibbs 2020, sp. nov.

Lasioglossum (Dialictus) julipile sp. nov. urn:lsid:zoobank.org:act: A8597CBD-1211-418D-99EE-1741EDB814E9 Figs 46– 48, 90E, 94C, 117B Diagnosis Females of Lasioglossum julipile sp. nov. can be recognized by the characters for the Lasioglossum clematisellum species complex (below), in addition to most of the body with very extensive, dense tomentum, and scutum with densely plumose hair. They are most similar to L. pallidellum, L. clavicorne sp. nov., and L. clastipedion sp. nov. Females of L. pallidellum have the metapostnotum rounded with rugae not reaching the posterior margin. Females of L. clavicorne sp. nov. have the scutum with numerous thin and weakly plumose hairs and are larger (5 mm). Females of L. clastipedion sp. nov. have the head and mesosoma slightly duller and more densely punctate (i ≤ 2 pd). Males of L. julipile sp. nov. can be recognized by the characters for the Lasioglossum clematisellum species complex (below), in addition to the frons with distinctly separated punctures (i ≤ 1 pd), propodeum lateral face rugulose, T2–4 with basolateral tomentum, and mesosoma with all hair densely plumose, appearing thickened. They are most similar to L. clematisellum, L. perditum sp. nov., and L. clastipedion sp. nov. Males of L. clematisellum and L. clastipedion sp. nov. have the frons slightly duller and more densely punctate (i <1 pd). Males of L. clematisellum also have the scutum with most hairs weakly plumose and T2–4 without basolateral tomentum. Males of L. perditum sp. nov. have the frons more sparsely punctate (i=1–3 pd) and propodeum lateral face smooth and tessellate. Etymology The specific epithet julipile is formed from the Latin noun ‘ iulus ’ (‘catkin’) and the adjective ‘ pile ’ (‘haired’). It refers to the densely plumose hair of this species, which resembles willow catkins. An appropriate translation would be the catkin-haired sweat bee.
